The family includes the original GSO-580 fixed-wing aircraft engine series, as well as the later SO-580 and VSO-580 helicopter engines. There is no non-supercharged, non-geared version of the engine, which would have been designated O-580 and therefore the base model is the GSO-580.[1][2]
The GSO-580 family of engines covers a range from 375 hp (280 kW) to 400 hp (298 kW). All have a displacement of 578 cubic inches (9.47 litres) and the cylinders have air-cooled heads. Compared to other horizontally opposed engines of similar displacement this family of engines produces high output power by supercharging and high maximum rpm, at the cost of higher weight.[1][2]
The GSO-580 series was certified under Type Certificate 256, while the SO-580 and VSO-580 series were certified under type certificate 285. Both were manufactured under Production Certificate No. 3.[1][2]
